Add August Matins readings for SanctiM-track saints

13 of August's 16 SanctiM-track saints authored, including the Duplex
I class feasts of St. Lawrence and the Assumption of the B.V.M. The
Assumption's presence confirms this app's calendar already maps fixed
BVM feasts, despite an older note in the parent workspace CLAUDE.md
suggesting otherwise -- flagged in memory as stale documentation to
verify against, not trust blindly. 3 saints left unsourced (Common-only
or Nocturn-1-only vigil content).

+        Quidnam Machabǽi? Horum enim nómine dies festus præsénti frequéntia celebrátur. Qui,
+        etsi apud multos non sunt in honóre, quod illud certámen post Christum non
+        suscepérunt; tamen digni sunt qui ab ómnibus honoréntur, quia pro pátriis légibus et
+        institútis fortes constantésque se præbuérunt. Nam qui martýrium subiére ante Christi
+        passiónem, quid factúri erant, si post Christum persecutiónem passi fuíssent, ejúsque
+        mortem, nostræ salútis causa suscéptam, ad imitándum propósitam habuíssent? Quorum
+        enim, nullo propósito exémplo, talis tántaque virtus fuit; an non ii, exémplum illud
+        intuéntes, fórtius in certámen descendíssent? Quin étiam mýstica quædam et occúlta
+        rátio, mihi quidem atque ómnibus Dei amatóribus valde probábilis est, néminem eórum qui
+        ante Christi advéntum martýrio consummáti sunt, id sine fide in Christum cónsequi
+        potuísse.

+        What were the Machabees? For it is under their name that the Festival at which you are
+        this day assembled is kept. It is true that many persons do not hold them in honour,
+        because they fought before the coming of Christ; nevertheless they deserve to be
+        venerated by all men, for they bore themselves bravely and faithfully in defence of the
+        laws and ordinances of their people. They that underwent martyrdom before Christ came,
+        what would not have been their deeds, if they had suffered persecution after He came, and
+        had had before them for a pattern the Death which He embraced for the sake of man's
+        salvation? With no example to lead them, their bravery was what it was; had they had the
+        example before their eyes, would they not have gone down with double nerve to the battle?
+        There is a mystic and subtle idea, which seemeth very likely to me and to all lovers of
+        God, that none of those who were crowned with martyrdom before Christ came, could have
+        been so, unless they had had faith in Christ.
